Double-row conveyor belt feeding apparatus and packaging box transportation device and method for using same

A double-row conveyor belt feeding apparatus, comprising:

• a charging conveyor belt, corresponding to a first conveyor belt and a second conveyor belt, and configured to convey box bodies toward the first conveyor belt and the second conveyor belt;
• a box body limiting baffle, located at an exit position of the charging conveyor belt, and configured to be driven to move to block the box bodies from entering the first conveyor belt and the second conveyor belt;
• box body limiting push rods, disposed on two lateral sides of the charging conveyor belt, wherein the box body limiting push rods correspond to a third row of box bodies that are on the charging conveyor belt and are close to the box body limiting baffle;
• and
• box body moving push rods, disposed on the two lateral sides of the charging conveyor belt, wherein the box body moving push rods correspond to a second row of box bodies that are on the charging conveyor belt and are close to the box body limiting baffle,
• wherein the box body moving push rods are configured to be driven to push a first row of box bodies to move by pushing the second row of box bodies, so as to make the first row of box bodies move onto the first conveyor belt;
• and
• after the first row of box bodies move onto the first conveyor belt, the box body moving push rods are configured to be driven to cause the second row of box bodies to move backwards onto the second conveyor belt, so as to make the second row of box bodies move onto the second conveyor belt.
